1. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?
- A. normal
- B. elevated
- C. low
- D. unrelated to the pH
Correct answer: B
Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
2. A nurse is caring for a patient in the step-down unit. The patient has signs of increased intracranial pressure. Which of the following is not a sign of increased intracranial pressure?
- A. Bradycardia
- B. Increased pupil size bilaterally
- C. Change in LOC
- D. Vomiting
Correct answer: B
Rationale: The correct answer is 'Increased pupil size bilaterally.' When assessing for signs of increased intracranial pressure, bilateral pupil dilation is not typically associated with this condition. Instead, unilateral pupil changes, especially one pupil becoming dilated or non-reactive while the other remains normal, are indicative of increased ICP. Bradycardia, a change in level of consciousness (LOC), and vomiting are commonly seen in patients with increased intracranial pressure due to the brain's response to the rising pressure. Therefore, the presence of bilateral pupil dilation goes against the typical pattern observed in patients with increased intracranial pressure.
3. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
- A. metastatic liver cancer
- B. gram-negative septicemia
- C. pernicious anemia
- D. iron-deficiency anemia
Correct answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding compared to the other conditions listed. Pernicious anemia is a condition resulting from vitamin B12 deficiency due to the absence of intrinsic factor, necessary for B12 absorption. While pernicious anemia can lead to neurological issues, it is not directly linked to an increased risk of bleeding. Metastatic liver cancer can cause liver dysfunction leading to coagulopathy, gram-negative septicemia can result in disseminated intravascular coagulation (DIC), and iron-deficiency anemia can lead to microcytic hypochromic red blood cells, increasing the risk of bleeding. Therefore, pernicious anemia is the least likely to be associated with an increased potential for bleeding out of the options provided.
4. Clomiphene is prescribed for a female client to treat infertility. The nurse is providing information to the client and her spouse about the medication and provides the couple with which information?
- A. If the oral tablets are not successful, the medication will be administered intravenously.
- B. The couple should engage in coitus at least every other day during treatment.
- C. The physician should be notified immediately if breast engorgement occurs.
- D. Multiple births occur in a small percentage of clomiphene-facilitated pregnancies.
Correct answer: D
Rationale: The correct answer is that multiple births (usually twins) occur in a small percentage (8% - 10%) of clomiphene-facilitated pregnancies. The couple should be informed about this potential outcome. Clomiphene is available in 50-mg tablets for oral use; there is no intravenous form of the medication. Breast engorgement is a common side effect of clomiphene that typically resolves after discontinuation of the medication. Ovulation usually happens 5 to 10 days after the last dose of clomiphene, and the couple is advised to engage in coitus at least every other day during this time. Therefore, choices A, B, and C are incorrect as they do not provide accurate information regarding clomiphene treatment for infertility.
5. What could be a possible cause for the symptoms experienced by the client in Question 28?
- A. iron deficiency
- B. folate deficiency
- C. peptic ulcer
- D. iron overload
Correct answer: A
Rationale: Given the client's symptoms of fatigue, shortness of breath, and lightheadedness, along with her gender and fad dieting, the most likely cause is iron deficiency. Iron deficiency commonly presents with these symptoms due to decreased oxygen-carrying capacity in the blood. Folate deficiency would typically present with different symptoms such as mouth sores and changes in skin, not fitting the client's presentation. Peptic ulcer would manifest with abdominal pain, not primarily with the symptoms described. Iron overload would present with symptoms such as joint pain and fatigue, which are not consistent with the client's presentation.
